Abstract

A lamp socket with decreased number of components is presented. The lamp socket includes a socket housing and a power supply member. The socket housing has a connecting hole. The power supply member includes a first lamp connecting terminal and a second lamp connecting terminal. The first lamp connecting terminal is inserted into the connecting hole and includes a first fixing portion that extends through the connecting hole and a first guide portion that extends from an end portion of the first fixing portion toward a first inner wall of the connecting hole. The second lamp connecting terminal is inserted into the connecting hole and includes a second fixing portion that extends through the connecting hole and a second guide portion that extends from an end portion of the second fixing portion toward a second inner wall of the connecting hole.
